Prepare the Prevention Plan (PP, applicable for Category 2 operations) or ask for the “Plan Particulier de Sécurité et de Protection de la Santé” (PPSPS, applicable for Category 1 operations) as well as any additional documents that may be required, identifying specific risks, and, in case a PP is required, submit a draft version to the Contractor. 

Warning: 
Category 1 operations: all the works and services executed towards the same objective: 
-    of a total volume greater than 4000 hours; and 
-    on a single, cordoned-off worksite; and 
-    involving several operating entities and not interfering with CERN’s operations.
Category 2 operations: all the works and services executed towards the same objective that are not Category 1 operations, including in particular: 
-    all works of a total volume of less than 4000 hours, or involving a single operating entity, regardless of the volume of activity; 
-    activities of any duration relating to the services and concessions.

For Category 1 operations, the PPSPS be submitted by the contractor and the corresponding Visite d’Inspection Commune (VIC) be held) before the start of works at CERN. 
For Category 2 operations, the PP must be signed before the start of works at CERN. 
CERN is responsible of the Safety of every person working on its site. In this respect, CERN has the obligation to ensure the Safety coordination of activities.  
The technical officer should seek support from HSE Unit when necessary, especially for specific matters such as radiation protection, asbestos etc. or for any help about the preparation of the PP. 
See HSE Unit website for more information on applicable Safety rules, available trainings etc.
Use the template available in CERN’s Safety forms website.
Technical Officer should have identified and understood the risks related to the performance of the works on site, and answer the questions “what”, “who”, “how”, “when”. This includes consideration of risks related to CERN site, co-activity and the performance of the activities at CERN. 

Complete the PP, including in particular risk mitigation actions, and submit it to the technical officer.

Review the document, in coordination with CERN’s HSE Unit, if needed.

Approve and sign the PP and upload it in EDMS and/or the Technical Officer’s equivalent filing system.

Tip: Legal obligation: 
For Category 1 operations, the PPSPS must be submitted by the contractor and the corresponding Visite d’Inspection Commune (VIC) be held) before the start of works at CERN. 
For Category 2 operations, the PP must be signed before the start of works at CERN. 

In case a PPSPS is required, the technical officer shall:
-     Check that the document is in line with the work foreseen;
-    Forward it to the Safety coordinator of the worksite.

Present the PP to the CERN team (work and services supervisors (WSS)) in charge of the supervision of operations.

Train the contractor’s personnel as well as subcontractor’s personnel about the provisions set forth in the PP.

Update the PP as often as needed (at least once per year), based on issues raised during follow-up meetings. 

Tip: Beware, irregular or no update of PP may be interpreted as default of Safety management.
Check regularly whether a new official template of the PP shall be used: CERN’s Safety forms website.
In order to facilitate the regular updates of PP, the Technical Officer may register information that is likely to change (eg. list of Contractor’s or subcontractor’s employees, list of certificates, etc.) in an annex to the PP. In doing so, only the annex(-es) would be updated.

Review, update the PP and re-submit it, as appropriate.

Sign the updated PP.

File the updated PP in EDMS and/or the Technical Officer’s equivalent filing system.
